At the beginning of winter semester 2009/2010 in the context of the Net Business Tools course at the Berlin University of Technology, we were given a task to evaluate, import and integrate certain functionalities of a web portal. This documentation provides a circumstantial description of the concept and the implementation of the import and integration process, in order to achieve a high usability solution.

The integration process will be applied with the Intrexx Xtreme software, which will be introduced in chapter \ref{chap:intrexx_intro}. Intrexx Xtreme is a software providing a standard framework that enables the creation and the management of web applications and portals, without any specialised knowledge required. 

Concerning to our task, the web portal created with Intrexx software, is operated by the \enquote{Landesbetrieb für Gebäudebewirtschaftung (LfG)} -- engl.: \textit{Management Agency for Real Estate Planning} (see chapter \ref{chap:lfg}). In the portal, an internal ordering system should have been developed, in which the data of suppliers and their products will be managed. This mechanism allowed the suppliers to administer and maintain their own products over the web portal.

In the chapter \ref{chap:prev_ach} it will be described more closely about the definition of this project, followed by chapter \ref{chap:implementation}, which specifies the implementation of the core functionalities importing and integrating the features using Intrexx Center module. For the implementation, a demo version of Intrexx Xtreme software has been used. Finally, the chapter \ref{chap:summary} summarizes the project work -- from evaluation to implementation.
